Safety-Critical Roles
Related Terms
Safety-Sensitive
ComplianceA designation for positions where impairment could directly cause injury, death, or environmental harm. Common examples include equipment operators, riggers, and drivers. Workers in these roles are typically subject to mandatory drug and alcohol testing under client and regulatory requirements.
IADC (International Association of Drilling Contractors)
ComplianceA global industry body that sets drilling standards, safety training programmes, and well control certifications. Subcontractors working on drilling sites often need IADC-recognised credentials to qualify for contracts. Holding valid IADC certifications can directly affect your crew's eligibility and your bid competitiveness.
Venting
ComplianceThe controlled release of gases from pipelines, vessels, or equipment during maintenance, commissioning, or decommissioning work. Subcontractors must follow site-specific venting procedures to remain compliant with environmental and safety regulations. Improper venting can result in work stoppages, fines, or removal from site.
Local Content Requirement
ComplianceA contractual or regulatory rule requiring subcontractors to hire local workers, source materials locally, or partner with regional firms. Non-compliance can disqualify you from bidding or trigger contract penalties. Common on projects funded by governments or national oil companies.
Metering Calibration
ComplianceThe process of verifying and adjusting flow meters, pressure gauges, and other measurement instruments to ensure accurate readings that meet regulatory and client standards — subcontractors providing metering services must maintain current calibration records as proof of compliance and to avoid liability for measurement disputes or billing discrepancies.
Chain-Of-Custody
ComplianceA documented record tracking who handled materials, samples, or equipment at every stage of a job. Subcontractors must maintain this trail to prove proper handling and avoid liability disputes. It is commonly required for soil samples, hazardous materials, and serialised equipment.
